Support for default plugin options?

[jboix]

I've noticed that the constructor of the player exclusively considers the plugins' options passed directly through the constructor parameters. Ideally, I was looking to configure default plugins for all player instances by doing something like this:

videojs.options.plugins = { eme: true };

Unfortunately, due to the current plugin initialisation approach, this configuration does not influence the plugin setup for individual player instances.

video.js/src/js/player.js

Lines 504 to 508 in 2f1cc6c

	if (options.plugins) {
	Object.keys(options.plugins).forEach((name) => {
	this[name](options.plugins[name]);
	});
	}

Is the current design intentional, or would you consider a change like this?

if (this.options_.plugins) {
  Object.keys(this.options_.plugins).forEach((name) => { 
    this[name](this.options_.plugins[name]); 
  });
}
